Description

Set of apparatus for carrying out 28 fundamental student experiments on electricity.
Stored in a tough Gratnells tray with foam inlay featuring recesses moulded
to the shape of the apparatus and covered by a transparent lid.

Circuits are
assembled using components in plug-in housings plugged into a plug-in board.
Power is supplied via 2 D-cell, LR20, 1.5 V batteries (batteries not included)
or via an external power supply.
